I'm not sure. On my remote box I usually start irssi by hand because it
only ceases if the machine is rebooted. ;-)

The current alias itself would probably cause problems in
a crontab. But you could maybe wrap it into a modified if that only
calls the alias if the pgrep command returns an empty result.
